分词的语态
1)通常,现在分词表示主动,过去分词表示被动,例如:
He is the man giving you the money. (= who gave you…) 他就是给你钱的那个人。
He is the man stopped by the car. ( = who was stopped by…)
他就是那个被车拦住的人。
2)不及物动词的过去分词表示动作已经发生
gone, fallen, retired, grown-up, escaped, faded, returned
例: a well-read person. 一个读过许多书的人
a much-travelled may 一个去过许多地方的人
a burnt-out match 烧完了的火柴
条件状语从句
连接词主要有 if, unless, as/so long as, on condition that 等。
if引导的条件句有真实条件句和非真实条件句两种。非真实条件句已在虚拟语气中阐述。
unless = if not.
Let‘s go out for a walk unless you are too tired.
If you are not too tied, let‘s go out for a walk.
典型例题
You will be late ___ you leave immediately.
A. unless B. until C. if D. or
答案A. 句意:除非你立即走,否则你就回迟到的。可转化为 If you dong leave immediately, you will be
late. B、D句意不对,or表转折,句子如为 You leave immediately or you will be late.
